Abstract
It is a technical common knowledge that a chaplet used in casting of a hollow casting is fusion-bonded with the melt and is incorporated into the casting. However, the adhesion between the chaplet and the casting body is not necessarily satisfactory, thereby incurring the strength reduction of a thin-wall hollow casting. A core for a thin-wall hollow casting according to the present invention is provided with a chaplet mounted thereon. The chaplet has arcuate portionwith a gapand a plurality of projectionsfrom an outer peripheral of the arcuate portion and is in contact with an inner wallof a mold. The entire arcuate portion of the chaplet is included in a grooveformed around an outer peripheral portion of the core body. Only the projectionsof the chaplet protrude from the core body, when the chaplet is inserted in the groove.
